QUESTION 69What paragraph best describes Pulse Code Modulation (PCM)?

A. PCM converts analog sound into digital form by sampling the analog sound 16000 times per second andconverting each sample into a numeric code. The Nyquist theorem states that when sampling an analogsignal at twice the rate of the highest frequency of interest, one can accurately reconstruct that signal backinto its analog form. Since most speech content is below 4000 Hz (4 kHz), the sampling rate needed is16000 times per second (225 microseconds between samples). The transmission rate is obtained bymultiplying 8000 samples per second times 8 bits per sample, giving 64,000 bits per second.

B. PCM converts analog sound into digital form by sampling the analog sound 8000 times per second andconverting each sample into a numeric code. The Nyquist theorem states that when sampling an analogsignal at twice the rate of the highest frequency of interest, one can accurately reconstruct that signal backinto its analog form. Since most speech content is below 4000 Hz (4 kHz), the sampling rate needed is 8000times per second (125 microseconds between samples). The transmission rate is obtained by multiplying8000 samples per second times 8 bits per sample, giving 64,000 bits per second.

C. PCM converts analog sound into digital form by sampling the analog sound 8000 times per second andconverting each sample into a numeric code. The Bellman Ford theorem states that when sampling ananalog signal at twice the rate of the highest frequency of interest, one can accurately reconstruct thatsignal back into its analog form. Since most speech content is below 4000 Hz (4 kHz), the sampling rateneeded is 8000 times per second (125 microseconds between samples). The transmission rate is obtainedby multiplying 8000 samples per second times 8 bits per sample, giving 64,000 bits per second.

D. All of above are correct and it depends what type of CODEC is used.

QUESTION 222What paragraph best describes Pulse Code Modulation (PCM)?

A. PCM converts analog sound into digital form by sampling the analog sound 16000 times per second andconverting each sampleinto a numeric code. The Nyquist theorem states that when sampling an analog signal at twice the rate ofthe highest frequency ofinterest, one can accurately reconstruct that signal back into its analog form. Since most speech content isbelow 4000 Hz (4 kHz),the sampling rate needed is 16000 times per second (225 microseconds between samples). Thetransmission rate is obtained bymultiplying 8000 samples per second times 8 bits per sample, giving 64,000 bits per second.

B. PCM converts analog sound into digital form by sampling the analog sound 8000 times per second andconverting each sampleinto a numeric code. The Nyquist theorem states that when sampling an analog signal at twice the rate ofthe highest frequency ofinterest, one can accurately reconstruct that signal back into its analog form. Since most speech content isbelow 4000 Hz (4 kHz),

the sampling rate needed is 8000 times per second (125 microseconds between samples). Thetransmission rate is obtained bymultiplying 8000 samples per second times 8 bits per sample, giving 64,000 bits per second.

C. PCM converts analog sound into digital form by sampling the analog sound 8000 times per second andconverting each sampleinto a numeric code. The Bellman Ford theorem states that when sampling an analog signal at twice therate of the highestfrequency of interest, one can accurately reconstruct that signal back into its analog form. Since mostspeech content is below4000 Hz (4 kHz), the sampling rate needed is 8000 times per second (125 microseconds betweensamples). The transmissionrate is obtained by multiplying 8000 samples per second times 8 bits per sample, giving 64,000 bits persecond.

D. All of above are correct and it depends what type of CODEC is used.
